Canon might have the edge in autofocus today, with dual-pixel AF (and quad-pixel rumoured to be on the way… eventually) and possibly even beating out Sony’s Eye AF face detection. They’re even bringing back the Eye Controlled Autofocus System for the EOS R3. But back in the early 80s, autofocus wasn’t something you really heard much about… From any brand.
In fact, the first SLR with autofocus wasn’t released until 1985. But that doesn’t mean autofocus wasn’t available. Canon actually made autofocus lenses for their FD mount cameras. They weren’t cheap and they weren’t particularly common but they did exist, as this video from Kai Wong demonstrates. And it still works on today’s mirrorless cameras.
